How to Prevent IP Spoofing of a Website

IP spoofing was a lot more serious exploit than it is now, but it continues to be a cause of concern for webmasters. Although you can never be safe from them attacks, there are things you can do to add a level of protection to your website.

1: Understand the risks. If you do not understand what it is, IP Spoofing is the use of different types software to change the destination address in the IP packets header. These packets are sent over an offline network (packets in offline networks are also known as datagrams), which makes them suitable for handling. The IP or IP modes TCP spoofing (the latter is not a problem nowadays) is constantly being reduced to improve internet security and develop new protocols, but there are still people using it for malicious purposes. The most common violations of IP Spoofing today are:

>> IP user authentication based exploits - where the attacker shares the IP of the network he is trying to access

>> Denial-of-service attacks - Direct, where the attacker modifies the destination in the IP packets by sending them to the destination address, or indirect, where the attacker sends requests to different reflectors / amplificators, with the header modified to indicate that the the target is the source of the package.
